Eric Temple Bell (1883–1960) was a Scottish-born mathematician, mathematician, and science fiction writer who made significant contributions to mathematics and its popularization. He is perhaps best known for his work in the fields of number theory, analysis, and the theory of functions. In addition to his academic work, Bell was a prolific writer and authored numerous books aimed at a general audience, making complex mathematical concepts accessible to non-specialists.

As of my last knowledge update in October 2023, Eugenia O'Reilly-Regueiro does not appear to be a widely recognized public figure, historical figure, or concept in mainstream discourse. It's possible that she is a private individual or a name that has come into prominence after my training cutoff.

Frank P. Ramsey (1903–1930) was a British mathematician, philosopher, and economist known for his contributions to various fields, including mathematics, logic, and decision theory. Despite his short life, he made significant advancements in several areas: 1. **Mathematics**: Ramsey is best known for his work in combinatorial mathematics. The Ramsey theory, which deals with conditions under which a certain order must appear in structures, is named after him.

John Riordan (1905–1982) was an American mathematician known for his work in combinatorics, generating functions, and number theory. He made significant contributions to the field, particularly in the areas of combinatorial methods and the study of special functions associated with mathematical sequences.

Heiko Harborth is a German mathematician known for his contributions to discrete mathematics, graph theory, and combinatorics. His research often focuses on topics related to graph coloring, extremal graph theory, and combinatorial algorithms. Harborth has authored and co-authored numerous papers and works in these areas, and he is recognized for his work in studying properties of graphs and their applications in various mathematical contexts.

Federico Rodriguez Hertz does not appear to be a widely recognized figure or term in public sources as of my last update in October 2023. It's possible that he could be a private individual or a lesser-known figure in a specific field. If he has gained notoriety or relevance after that date, I would not have that information.

The cutoff frequency, often denoted as \( f_c \), is a fundamental parameter in the field of signal processing and filter design. It refers to the frequency at which the output of a filter or a system begins to attenuate significantly compared to its response at lower frequencies. Typically, it marks the boundary between passband and stopband in a filter.

Hugo Hadwiger was a notable Swiss mathematician known for his contributions to several areas of mathematics, particularly in the fields of topology, geometry, and graph theory. He is perhaps best known for Hadwiger's theorem and Hadwiger's conjecture, which relate to the properties of graph colorings and the connections between different types of geometric figures. His work has had a lasting impact on mathematical research and theory.

Imre Bárány is a Hungarian mathematician known for his work in combinatorics, particularly in areas related to convex geometry and discrete geometry. He has made significant contributions to various aspects of these fields, often focusing on the interplay between combinatorial structures and geometric properties.

J. H. van Lint (Jan H. van Lint) is a notable figure in the fields of mathematics and combinatorics. He is particularly known for his contributions to graph theory, coding theory, and combinatorial designs. Van Lint has authored several influential books and research papers, often co-authoring works with other mathematicians. His book "Introduction to Coding Theory," co-authored with J. A. H. H.

Defamation is not fraud because no one has a legal agreement with the public by default to provide true facts only. If defamation was legal, there would be so many false accusations and fake evidence of the same, that most people would actually learn to think critically and not believe something until it has truly been verified. If a majority of people gain this skill, their critical thinking would be the predominant opinion, and anybody blindly believing things would have to be willfully blind.

James William Peter Hirschfeld does not appear to be a widely recognized public figure or concept based on the information available up to October 2023. It’s possible that he may be a private individual or a figure in a specific niche that is not broadly known.

The Efficient Frontier is a key concept in modern portfolio theory, introduced by Harry Markowitz in the 1950s. It represents a graphical depiction of the set of optimal portfolios that offer the highest expected return for a given level of risk, or the lowest risk for a given level of expected return. Here are some important aspects of the Efficient Frontier: 1. **Risk vs.

A government not supported by the majority cannot sustain itself without tyranny. They will eventually get rid of the current government and laws, even amend the constitution, if needed, to get their way. Thus it is impossible to maintain libertarianism by restricting voters or their power.

To achieve a libertarian country, either the majority of people in an existing country must be convinced of its merits, or libertarians must come together to form a new nation. And if the majority is libertarian, they will vote as such, maintaining the minarchy.

Jennifer Morse is a notable mathematician recognized for her work in the areas of dynamical systems and topology. She has made significant contributions to the understanding of complex systems and the mathematical theories underlying them. Morse has also been involved in various academic and educational initiatives, promoting mathematics and supporting the mathematical community.

Jinyoung Park is a mathematician known for contributions in the field of mathematics, specifically in areas such as algebra, geometry, or topology.

In mathematics, localization is a technique used to focus on a particular subset of a mathematical structure or to analyze properties of functions, spaces, or objects at a certain point or region. The concept is prevalent in various areas of mathematics, particularly in algebra, topology, and analysis.
